Computer isn't fully powering on after I wake it up. It doesn't happen every time I put it to sleep and wake it up, but it usually happens about 1-3 times a day, depending on how much I use it, in other words, regularly random. haha

It started happening after I got a new hard drive installed and my old one crashed. Since then we've put in two different hard drives, an apple 80GB and an aftermarket 100GB, and a new logic board. I've sent it into apple 3 times. Still no answer to what this could be... any ideas?
